Specification of Letters Patent.

Patented May 14, 1912.

Application filed April 27, 1911. Serial No. 623,651

To all whom it may concern Be it known that we, l/VILLIAM MARSHALL and NEWTON SIMIsoN, citizens of the United States, residing at Des hloines, in the county of Polk and State of Iowa, have invented a certain new and useful Anchor, of which the following is a specification.

The object of our invention is to provide an anchor for telegraph poles and the like of simple, durable and inexpensive construction which can be easily and firmly fixed in the ground, and which has parts which can be driven into the ground at right angles to a guy wire or the like secured to said an chor without disturbing the ground into which said parts are driven.

More particularly it is our object to pro- 'vide an anchor of such a kind having parts which may be readily and easily driven into the solid earth at the bottom of the hole at right angles to such a guy wire.

Another object of our invention is to provide means whereby such parts at the bottom of a hole may be easily and readily driven into the earth, said means being operated from the surface of the earth.

A further object of our device is to provide such an anchor which may be easily and readily taken apart and placed in a small space for storage or transportation, and all parts of which except the base plate, anchor plates and anchor rod may be removed after the anchor is set, and used again.

Our invention consists in certain details in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which- Figure 1 shows a side elevation of an anchor embodying our invention. Fig. 2 shows a top or plan view of the base plate of the anchor with the movable anchor plates inserted therein. Fig. 3 shows a transverse central sectional view of the same with the Fig. 4 shows a plan view of one of the anchor plates. Fig. 5 shows a perspective view of the slotted wedge block, and Fig. 6 shows a perspective view of the tamping or driving device.

Our improved anchor is preferably constructed wholly of metal.

In the accompanying drawings, we have used the reference numeral 10 to indicate a base plate which is shown in the drawing to be cylindrical in shape but which may be made in other forms. The base plate 10 is constructed with the central opening 11 designed to receive the anchor rod 12 which is provided with a head 13 at its lower end by which the rod is held in the base plate. The anchor rod 12 is constructed with a loop 12 at its upper end. The base plate is constructed with slots 14 on opposite sides of the opening 11, which slots extend from points spaced apart from the opening 11 to the outer edge of the base plate and are designed to receive the wedge block hereinafter described. The base block 10 is also constructed with a slot 16 extending through said block horizontally in the same direction as the slots 14, designed to receive the anchor plates 15 hereinafter described. The base plate is solid for a short distance around the opening 11. The base plate 10 is provided with flanges 17 and 18 around its outer circumference adjacent to the slot 16, said flanges extending approximately half way across the slot 16 and being located on the upper side of the slot 16 on one side of the base plate and on the lower side of said slot on the other of said base plate, as shown in Fig. 3.

Slidingly received in the slot 16 on the respective sides of the base plate 10 are anchor plates 15, the thickness of which is substantially half the width of the slot 16. The plates 15 are substantially rectangular in shape and somewhat shorter than the diameter of the base plate 10. The outer ends of the plates 15 are constructed in the form of a circle with its center at the center of the base plate 10 and with a diameter slightly less than the length of the base plate 10, in order that the anchor plates 15 may be wholly received in the slot 16 with their ends resting against the flanges 17 and 18. The anchor plates 15 are provided with longitudinal slots 18 designed to slidingly receive the solid central portion of the base plate 10, the portion of said anchor plates adjacent to the inner end of the slot being preferably curved as shown in Fig. 4. The anchor plates 15 are slidingly received on each side of the base plate 10 within the slot 16 and when inserted therein rest substantially one above the other as shown in Fig. 3. For driving the anchor plates 15 from their position within the base plate 10, we provide a wedge block 19 which is substantially triangular in cross section and is constructed with a slot 20 extending from its apex to a point spaced apart from its base, the said slot being designed to slidingly receive the solid centralportion of the base block, the apex of the wedge block thus being'forked. We preferably construct the wedge block 19 with a projection 21 cen trally located on its base, said projection being substantially cylindrical in cross section, which projection receives the force of the blow when the wedge is being driven. Near the upper end of the projection 21, we provide laterally extending lugs 21 for a purpose hereinafter explained. The base of the wedge block 19 and the projection 21 are provided with a central slot 21, elongated in a direction at right angles to the base of the wedge block 19, and extending from the outer end of the projection 21 to the slot20. The edges of the base block from the apex of the base are preferably rounded, as shown in Fig. 5, or may be rounded except near the base as shown in Fig. 1. The wedge block 19 is mounted on the anchor rod 12 with its apex received in the slots 14 and is designed to be driven downwardly to spread apart the anchor plates 15.

We provide a tamping or driving device comprising an arm or handler22, a base or driving portion 23, and a portion 24 at the upper end of the handle for engaging the wedge block and withdrawing it from the hole in which the anchor is placed. The base portion 23 is constructed with a longitudinal slot 25 substantially parallel with the arm 22, which arm 22 is secured to the upper end of the base portion 23 at the side of the slot 25. The slot 25 is of proper size to slidingly receive the anchor rod 12. At the upper end of the handle 23 is a portion 24 constructed with a slot similar to the slot 25 designed to slidingly receive the anchor rod 12. The end of the portion 24 is constructed with a cylindrical opening shown in Fig. 1, designed to receive the projection 21. Formed in the side of the portion 24 are slots 26 which with the lugs 21 form bayonet joints when the projection 21 is received in the opening in the portion 24.

- The inner end of the slot 26 is laterally elongated in the direction of the longitudinal axis of the handle 22. The portion24 is designed to withdraw the wedge block '19 from the hole in which the anchor is planted. The projection 21 is received in the cylindrical opening in the portion 24 and the lugs 21". are received in the slots 26 when it is desired to withdraw the'wedge.

In assembling and planting our anchor, we insert the anchor rod 12 in the opening 11 and form the loop 12". Te then insert the anchor plates 15 in the slot 16 on the opposite sides of the base plate 10. We then mount the wedge block 19 on the anchor rod 12 with its forkedend received in the slots 14. The tamping device is then mounted on the anchor rod 12 with the said rod received in the slot 25. The anchor is then placed at the bottom of a hole and the anchor plates 15 may be forced apart by driving the wedge block 19 downwardly with the tamp ing device. After the anchor plates 15 are driven into the ground at the sides of the hole the tamping device is removed and the withdrawing device is placed over the anchor rod 12 with said rod received in the slot provided therefor. The projection 21 is received in the cylindrical opening in the portion 24 and the lugs 21 are received in the slots 26. The handle 22 is given a slight rotary motion, and the portion 24 is thereby locked in position by means of the bayonet joints formed by the lugs 21 and the slots 26. The purpose of the extension at the inner end of the slot 26 hereinbeforedescribed is now clear. By means of said extension, a certain play or longitudinal movement of the portion 24 on the extension or projection 21 is permitted and thereby a jerking movement may be employed in withdrawing the wedge block 19. When the wedge block 19 and the clamping device are removed from thehole, the latter may be filled and a guy wire secured to. the loop12 at the upper end of the anchor rod 12.

The special advantage of our device lies in its means for driving the anchor plates into the solid ground from a position above the surface of the ground, thus leaving the anchor firmly embedded in the ground which has not been disturbed by recent dig.- ging, and also in the construction and arrangement of the parts of our device, which enables the user to withdraw from the hole in the ground all the parts except those necessary fora permanent anchor, and which makes it possible to use the other parts again.

The advantages of the wedge block over. ordinary means for forcing the anchor plates or similar devices into the solid ground at the side of the hole are considerable. The power from the wedge block is applied directly to the inner ends of the anchor plates and a blow on the upper end of the wedge block is directly imparted to the anchor plates.
